In addition to Pt100 resistance thermometers, it can also process signals from typical thermocouples. Thus temperatures from -200... +1,500 C (-328... +2,732 F) can be measured. The explosion proof version is only for measuring Pt100 resistance thermometers available. Through its high accuracy of 0.03 K in ranges from -100... +150 C (-148... +302 F), this instrument can also be used as a reference instrument in biotechnology, pharmaceutical and food industries. The CTH6500 is thus also ideal for all service and maintenance tasks. In this way it is possible to reduce measuring errors to a minimum and ensure a high display accuracy. Additional fields of application The instrument has been primarily designed for temperature measurement, though it can, with the appropriate probes, also be used for: Humidity measurement with a combined temperaturehumidity probe Flow measurement from 0.1... 40 m/s with a vane sensor The calibration and adjustment possibilities above are also applicable to these measurement parameters. Low-drift measuring amplifiers ensure small measurement errors, while easy-to-use adjustment features considerably simplify adjustments and calibrations: Calibration by code for fast setting of standard probes via identification numbers Physical calibration of probe and display at one, two or three different temperatures WIKA data sheet CT 55.10 09/2017 Page 1 of 6 Data sheets showing similar products: Hand-held thermometer; models CTH6300, CTH63I0; see data sheet CT 51.05
